. Specficajzonof` Letters Patent No. 8,239, dated July 22,` 1851.

State ofMassachusetts, have invented a new and useful Improvement in Pumps for Elevating `Water; and Ido hereby declare that the same is fully described and represented in the following specification and accompanying drawings, letters, figures, and references thereof.

Of the said drawings, Figure l, represents y a `vertical and central section of our im* proved pump, taken through the `nose or` `first.

In the said drawings, A represents `the pump barrel, in which areplaced -two hollow cylinders B, C, and whichbyrings of packing a, b, `are made to closelyfit within the interior of the barrel. Between each two rings 0;, .7), there a space c, extending entirely around the outer surface of the cylinder, and for thepurpose of holding tallow or other suitable Vunctuous material, which bearing against the inner surface of the pump barrel mayfserve to cause the boxes B C, to work watertight. Each of said boxes B C, is provided with two butterfly valves d, e, or f, g, which are respectively hinged to a cross bar 71 or i, which extends ldiametrically acrossthe lower part of the ox. f

Instead `of the `butterfly valves when closed down being made to rest on a ledge or flanch in the usual way, they are inclined a litt-le, and made ongtheir external edges to rest against the verticalinside` surface of the box to which they belong. Each valve is fastened to a long rod E, or F. The rod E, to which the lower box is attached, works freely through a pipe G, attached to the internal surface of the upper box, and such rod is made hollow or tubular so asto receive another rod H, which extends downward entirely through it, and has two arms I, K, extended upward from its lower end, and respectively and directly under the two lower valves of the lower box. Apcollar M,

is fixed upon the rod H, and made "to rest upon the top ofthe rod or stem of the lower valve, and to be fitted air tight thereupon. Each of the valve rods,has`an armxN, or O, extended from it, which arm is connected to a vibratinglever P, by a Vconnecting rodi or link or links Q, or R, the samebeingjointed and recede from one another.

together in such manner as to create a reciprocatlng vertical motion of the boxes, when the lever beam is vibrated. The said lever beam is fixed upon a horizontal shaft S,

which has a crank T, fixed to it, for the purnTED STATES PATENT OFFICE H N pose of enablinga person to put it in moi tion. In order to sustain or guide the upper end of each valve rod, a rod U, is ex'- tendedupwardfrom it, and made to slide through a bar V, or W, extended across the upper part of the head part X, of the barrel of the pump, or thatpart from which the nose Y, extends. i

f `In the operation' of the pump, the two boxes are madeto alternately approach to, This will cause a constant stream of water to flow out of the nose. By laying hold of, and lifting the rod H, at any time, we can elevate the arms on its lower end against the valves of the lower box, so as to raise said valves and allow what water `may beabove them, or between them and the valves of the up per box to escape or flow downward through the pump, and back into the source from which the water was taken. At the same time air will pass down between the rods F, and H, (in consequence of the shoulder or collar M, being elevated above its seat on the top of the `rod E,) and into that part of the pump which is below the lower box, and will cause all the water which may be in that part of the pump which is below the lower box, to descend into the well or source from which the water is derived.

I would remark that by so making the arms, which extend upward from the low,er end of the rod H, that when the collar rests upon itsseat, there shall be a short distance between the tops of said arms, `and the lower surfaces `of thelower valve. I am enabled to raise the rod H, a little, and so as to lift its collar from its seat or top of the rod F, without at the same time` raising the lower valves. Thus I can at any time allow air to pass down into that part of the pump which is below the lower valve,

and free such part from water while I re-` from water, in order to prevent freezing of the same.l

What I claim as my invention or improve- In testimony whereof I have hereto set ment is as follows: my signature this second day of May, A. D.

I claim the rod H, and its arms or other 1851. equivalent contrivanoes, and its Valve collar, JOSEPH F FLANDERS 5 as applied to or combined with the rod E, of i the lower box, and the valve or valves made Witnesses: to operate therewith substantially as above R.
